P00B7 on MINI
Engine Coolant Flow Low/Performance
P00B7 on MINI vehicles indicates engine coolant flow low/performance. Au7o has documented this code across 1 MINI model — most commonly on Countryman. P00B7 means the powertrain control module has determined that coolant flow through the engine's cooling system is too low or not performing as expected. The computer compares signals — typically from the engine coolant temperature sensor and a second temperature sensor (such as the radiator outlet) — and flags this code when the readings indicate coolant isn't circulating properly to manage engine temperature. Restricted flow can let the engine run hotter than designed, risking overheating. The cause is usually a thermostat, water pump, low coolant, or a sensor reading problem. Typical repair costs on MINI range from $400 to $1,000, depending on the specific model and root cause.
Common Causes of P00B7
- •Stuck or faulty thermostat
- •Low coolant level or air pockets in the system
- •Failing water pump (mechanical or electric)
- •Faulty engine coolant temperature or radiator temperature sensor
- •Clogged radiator, hoses, or coolant passages with sediment/debris
- •Coolant leak reducing system volume
- •Wiring/connector faults at the temperature sensors or PCM control issue
P00B7 on MINI by Model
MINI Countryman(1 issue)
- Electric Water Pump and Thermostat Failure2011-2016
The MINI Countryman with the N18 turbocharged engine develops electric water pump failures. The pump can fail internally without warning, leading to rapid overheating. The thermostat housing is also plastic and prone to cracking.

What does P00B7 mean on MINI?▼
P00B7 stands for "Engine Coolant Flow Low/Performance." P00B7 means the powertrain control module has determined that coolant flow through the engine's cooling system is too low or not performing as expected. The computer compares signals — typically from the engine coolant temperature sensor and a second temperature sensor (such as the radiator outlet) — and flags this code when the readings indicate coolant isn't circulating properly to manage engine temperature. Restricted flow can let the engine run hotter than designed, risking overheating. The cause is usually a thermostat, water pump, low coolant, or a sensor reading problem. On MINI specifically, this code is documented across 1 model.
What causes P00B7 on MINI vehicles?▼
Common causes on MINI: Stuck or faulty thermostat, Low coolant level or air pockets in the system, Failing water pump (mechanical or electric), Faulty engine coolant temperature or radiator temperature sensor, Clogged radiator, hoses, or coolant passages with sediment/debris. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P00B7 on a MINI?▼
Repair costs on MINI range from $400 to $1,000, depending on the specific model and root cause.
